Smile lines, those creases that frame our smiles and laughter, are a natural part of life and aging.
Also known as laugh lines or nasolabial folds, these lines typically run from the sides of the nose to the corners of the mouth. While they signify a life filled with expression and joy, many people seek ways to reduce their appearance for cosmetic reasons, aiming for smoother, more youthful-looking skin.
The good news is that whether you’re looking for natural remedies, advanced cosmetic procedures, or preventative measures, numerous options are available to address smile lines.
This guide explores the causes of smile lines and dives deep into the various methods available to diminish their appearance.
Understanding Smile Lines
What Exactly Are Smile Lines?
Smile lines, or nasolabial folds, are the creases extending from the sides of your nose down to the corners of your mouth. They are often more noticeable when you smile or laugh, hence the names. While subtle lines can be present even in younger individuals due to facial expressions, they tend to deepen and become more permanent over time as the skin loses elasticity and volume.
It’s important to distinguish these from “laugh lines” that can also refer to the crow’s feet wrinkles around the eyes, which appear when laughing or squinting.
Smile lines around the mouth are considered dynamic wrinkles initially, meaning they appear with movement, but can become static (permanent) wrinkles over time.
What Causes Smile Lines?
Several factors contribute to the formation and deepening of smile lines:
- Aging: As we age, our skin naturally loses collagen and elastin, the proteins responsible for its firmness, elasticity, and ability to bounce back. Cheekbones may flatten, and gravity pulls down looser skin, making folds more prominent. Facial fat loss also plays a role.
- Repeated Facial Expressions: The very act of smiling, laughing, frowning, and making other expressions causes the skin to fold repeatedly in the same places, eventually etching lines into the skin.
- Sun Damage: Exposure to the sun’s ultraviolet (UV) rays accelerates the breakdown of collagen and elastin, significantly contributing to premature aging and wrinkle formation.
- Smoking: Smoking introduces toxins that damage collagen and elastin, hindering the skin’s repair mechanisms and accelerating the aging process.
- Genetics: Your genetic makeup can predispose you to developing smile lines earlier or more prominently than others.
- Dehydration: Skin that lacks adequate hydration can appear less plump and more prone to showing lines.
- Weight Fluctuations: Significant weight loss can lead to looser skin, while weight gain can result in larger cheeks, both of which can accentuate nasolabial folds. Rapid fat loss, sometimes seen with weight loss injectables like Ozempic, Wegovy, or Mounjaro, can also increase the appearance of smile lines.
Natural Remedies and Lifestyle Adjustments
Before exploring more intensive treatments, several natural approaches and lifestyle changes can help minimize the appearance of smile lines and promote overall skin health.
Facial Exercises
Targeted facial exercises may help tighten the muscles around the mouth and eyes, potentially reducing the appearance of laugh lines. While consistency is key, here are a few exercises based on the provided information:
- Mouth Exercise 1 (Orbicularis Oris Strengthener):
- Hook index fingers into the corners of your mouth.
- Gently pull outwards about a quarter-inch.
- Resist with your fingers while using mouth muscles to tighten the corners towards each other.
- Hold for 5-10 seconds, relax, and repeat 10-25 times.
- Mouth Exercise 2 (Cheek Lifter):
- Place index fingertips on the laugh lines around your mouth.
- Smile as widely as possible with lips separated, applying pressure with fingers.
- Hold for 5-10 seconds, relax, and repeat 15-30 times.
- Mouth Exercise 3 (Resistance Smile):
- Partially separate lips and pull the corners of the mouth back towards your face, keeping lips parallel.
- Pull back as far as possible.
- Hold for 10 seconds, relax, and repeat 10-25 times.
- Eye Exercise (Crow’s Feet Reducer):
- Place thumbs near the outer corners of your eyes, fingers on top of your head.
- Close eyes tightly.
- While squeezing eyes shut, gently pull the outer corners away from each other and slightly upwards with your thumbs.
- Hold for 5-10 seconds, relax, and repeat 10-25 times.
(Note: Scientific evidence supporting the long-term effectiveness of facial exercises for wrinkle reduction is often debated, but they may offer some toning benefits).
Hydration and Diet
- Drink Plenty of Water: Keeping your body and skin well-hydrated helps maintain skin plumpness and elasticity. Aim for adequate daily water intake.
- Eat a Balanced Diet: A diet rich in nutrients, proteins, and antioxidants supports overall skin health. Avoid excessive caffeine and alcohol, which can have diuretic effects.
Skincare and Sun Protection
- Daily Skincare Routine:
- Cleanse gently twice daily to remove impurities without stripping natural oils.
- Use a moisturizer suited to your skin type to keep skin hydrated. Look for ingredients like hyaluronic acid.
- Consider incorporating facial massage into your routine. Gua sha massage might offer temporary de-puffing and tightening, but results aren’t permanent.
- Sun Protection is Crucial: Daily application of broad-spectrum sunscreen with SPF 30 or higher is one of the most effective ways to prevent premature aging, including smile lines. Reapply every two hours, or more often if sweating or swimming. Wear protective clothing and seek shade when possible. Wearing sunglasses can also prevent squinting, which contributes to lines.
Other Lifestyle Factors
- Don’t Smoke: Quitting smoking is vital for skin health, helping prevent further damage and allowing skin to repair.
- Get Adequate Sleep: Aim for regular, sufficient sleep to allow your body and skin to regenerate.
- Sleep Position: Sleeping on your back may help prevent sleep creases and work with gravity against lines. If you sleep on your side, try alternating sides.
- Avoid Irritating Products: Don’t use skincare products that sting or burn unless prescribed, as irritation can worsen signs of aging.
Topical Treatments
Over-the-counter (OTC) and prescription creams offer a non-invasive approach to reducing the appearance of fine lines, though results take time and consistent use.
- Retinoids (Retinol and Prescription Forms): Derived from Vitamin A, retinoids are well-studied for their ability to speed up cell turnover, boost collagen production, and improve the appearance of wrinkles. Consistent use (often 3-6 months) is needed to see significant results. Prescription-strength retinoids are more potent than OTC retinol.
- Vitamin C: A powerful antioxidant, Vitamin C helps protect skin from free radical damage (from sun and pollution), brightens the skin, and supports collagen synthesis.
- Peptides: These are short chains of amino acids that act as building blocks for proteins like collagen and elastin. Topical peptides signal the skin to produce more collagen, potentially improving firmness and reducing wrinkle depth.
- Hydroxy Acids (AHAs/BHAs): Acids like glycolic acid (AHA) can exfoliate the skin’s surface, revealing smoother skin and potentially stimulating collagen over time.
- Moisturizers: While not reversing wrinkles, good moisturizers (especially those with hyaluronic acid) plump the skin temporarily, making lines less noticeable.
Minimally Invasive Procedures
For more noticeable or faster results than topical treatments, several minimally invasive procedures are available.
Injectable Fillers
Dermal fillers are a popular choice for directly addressing the volume loss that contributes to smile lines. They are injected into the crease to plump the area and smooth the fold.
- Hyaluronic Acid (HA) Fillers: These are the most common type, using a substance naturally found in the skin. Brands include Juvéderm and Restylane. Results are often immediate and typically last 6-12 months. An advantage is that HA fillers can often be dissolved if results aren’t satisfactory. Repeated injections might stimulate some scar tissue, potentially leading to longer-lasting effects.
- Collagen-Stimulating Fillers: Options like Radiesse (Calcium Hydroxylapatite) and Sculptra (Poly-L-Lactic Acid) work by stimulating your body’s own collagen production over time, potentially offering longer-lasting results than HA fillers. These might be injected deeper. PMMA fillers (e.g., Bellafill) offer a more permanent solution but are used less commonly.
- Cost & Side Effects: Costs can range up to $1,000 or more per treatment. Potential side effects include temporary bruising, swelling, redness, headaches, and rare risks like allergic reactions, infection, or vascular occlusion. Removal procedures might be needed for complications and carry their own risks.
Botulinum Toxin Injections (Botox, Dysport, Xeomin, Daxxify)
While highly effective for dynamic wrinkles caused by muscle movement (like crow’s feet or frown lines), Botulinum toxin is less commonly used for nasolabial folds themselves.
However, it may sometimes be used strategically to relax specific muscles around the mouth that pull downwards, subtly improving the appearance of smile lines. It works by temporarily weakening muscle contractions.
Results appear within days and typically last about 3 months. Side effects can include temporary bruising, redness, headache, or irritation at the injection site. Costs vary depending on the amount used.
Skin Boosters
Skin boosters are micro-injections designed to deeply hydrate the skin and improve its quality, elasticity, and radiance from within, rather than adding volume like traditional fillers. They work by delivering substances like hyaluronic acid or polynucleotides directly into the skin, stimulating collagen and elastin production.
This improves the skin’s resilience and hydration, helping to soften smile lines. Examples include:
- Juvelook: Aims to revitalize and rejuvenate.
- Rejuran Healer: Uses polynucleotides to repair and strengthen skin cells.
- NCTF 135 HA: Focuses on hydration with hyaluronic acid.
- Profhilo: High concentration HA that hydrates and remodels skin structure to fight sagging.
- Gouri PCL: Stimulates natural collagen production for long-lasting firmness.
Choosing the right booster depends on individual needs, and consultation with a professional is recommended.
Laser Skin Resurfacing
Laser treatments remove the outermost layer of skin, revealing newer, smoother skin underneath and stimulating collagen production. This can reduce the appearance of wrinkles and skin spots.
- Types: Various lasers exist, including ablative (like CO2, which removes thin layers) and non-ablative (like Fraxel, which heats underlying tissue without removing the surface).
- Results & Recovery: Results develop over time as collagen builds. Recovery can involve swelling, redness, and downtime of 1-3 weeks depending on the laser’s intensity. Multiple sessions may be needed.
- Risks: Include pain, swelling, potential scarring, infection, and pigmentation changes.
- Cost: Can range from $1,750 to $2,300 per treatment.

High-Intensity Focused Ultrasound (HIFU) / Ultherapy
HIFU treatments like Ultherapy use focused ultrasound energy to heat deeper layers of the skin (the same layers addressed in surgical facelifts) without damaging the surface.

This stimulates the body’s natural collagen production process, leading to gradual skin lifting and tightening over several months. It’s particularly useful for addressing skin sagging that contributes to smile lines.
Radiofrequency (RF) Treatments (e.g., TempSure)
RF devices like TempSure deliver heat to the dermis (the layer beneath the skin surface) using radiofrequency energy. This heat stimulates new collagen growth and causes existing collagen to contract, leading to skin tightening.
- Results: Some immediate tightening may be visible, but the most significant improvement typically appears 4-6 weeks later as collagen rebuilds.
- Treatment Plan: Multiple sessions (e.g., four treatments spaced 2-4 weeks apart) are usually required, followed by maintenance touch-ups every 6-12 months.
- Benefits: Procedures can be quick (around 20 minutes) with minimal to no downtime.
Collagen Induction Therapy (Microneedling)
Microneedling uses a device with fine needles to create controlled micro-injuries in the skin. This process triggers the skin’s natural healing response, stimulating the production of new collagen and elastin. As the skin repairs, it can become firmer and smoother, potentially reducing the appearance of fine lines and wrinkles over time.
- Results: Results are gradual, often taking several months to become fully apparent.
- Treatment Plan: Multiple sessions (typically 3-6) are usually needed.
- Side Effects: Temporary redness, bruising, and swelling are common post-treatment.
Thread Lift
A thread lift involves inserting dissolvable threads under the skin to gently lift and reposition sagging tissue. The threads themselves also stimulate collagen production as they dissolve, further improving skin texture and firmness. This can help lift cheek contours and smooth smile lines. It’s often considered less invasive than a surgical facelift but provides more subtle results. This treatment may be better suited for faces that are more oval and less wide.
Chemical Peels
Chemical peels use acidic solutions to remove the damaged outer layers of skin, encouraging regeneration and revealing smoother, less wrinkled skin underneath. Peels vary in strength (superficial, medium, deep) depending on the depth of penetration and the desired results. They can help improve skin texture and reduce the appearance of fine lines.
Surgical Options
For the most dramatic and long-lasting results, particularly for significant sagging and deep folds, surgery may be considered.
Facelift (Rhytidectomy)
A facelift is the most comprehensive surgical procedure to address aging in the mid-to-lower face and neck.
It involves lifting and repositioning underlying tissues and removing excess skin to create a smoother, more youthful contour, effectively addressing deep smile lines and jowls. Eyelid surgery might be combined for overall facial rejuvenation.
- Results: Results are significant and long-lasting, though the natural aging process continues.
- Recovery: Requires significant downtime, often averaging around 3 months for full recovery.
- Risks: As with any surgery, risks include infection, scarring, bleeding, pain, nerve damage, and anesthesia complications.
- Cost: Facelifts are among the most expensive options, averaging over $7,000 in 2016, plus anesthesia and facility fees.
Choosing the Right Treatment
With so many options, selecting the best approach depends on individual factors like the severity of the lines, skin type, budget, desired results, tolerance for downtime, and overall health.
Consulting with a board-certified dermatologist or plastic surgeon is crucial. They can assess your specific situation, discuss the pros and cons of each suitable treatment, and help you create a personalized plan.
Frequently Asked Questions (FAQ)
Q: Can smile lines go away completely?
A: While treatments can significantly reduce the appearance of smile lines, completely eliminating them permanently, especially through natural means alone, is challenging due to the ongoing aging process and facial movements. Combining treatments with preventative measures yields the best long-term results.
Q: How can I get rid of smile lines naturally?
A: Natural approaches focus on prevention and minimizing appearance. This includes consistent sun protection, staying well-hydrated, maintaining a healthy lifestyle (diet, no smoking), practicing a good skincare routine with moisturizers (perhaps with ingredients like hyaluronic acid), and potentially trying facial exercises.
Q: Why do I have smile lines at a young age (e.g., 15 or 16)?
A: Seeing lines when smiling at a young age is often due to normal facial expressions and the way skin naturally folds during movement, rather than permanent wrinkles associated with aging. Genetics and dehydration can also play a role. These are usually dynamic lines visible only during expression.
Q: What’s the difference between skin boosters and fillers?
A: Dermal fillers are primarily used to add volume to specific areas, filling in creases or enhancing features. Skin boosters focus on improving overall skin quality, hydration, and elasticity through micro-injections of hydrating agents like hyaluronic acid, without significant volumization.
Q: Are treatments like Botox and fillers safe?
A: When performed by qualified and experienced medical professionals, treatments like Botox and FDA-approved dermal fillers are generally considered safe. However, potential side effects exist, ranging from common temporary issues like bruising and swelling to rarer but more serious complications like allergic reactions or infection. Discuss risks thoroughly with your provider.
Q: Do facial exercises really work?
A: Facial exercises aim to strengthen facial muscles to potentially lift and tighten the overlying skin. While some people report benefits, robust scientific evidence for their long-term effectiveness in significantly reducing established wrinkles is limited compared to medical treatments.
Q: Is face tape or gua sha effective for preventing smile lines?
A: Anti-wrinkle face tape aims to limit facial movement, but effectiveness is questionable as it would need to be worn constantly and doesn’t address underlying skin thinning or fat loss. Gua sha massage may offer temporary de-puffing and relaxation benefits, but results are not permanent for wrinkles.
Conclusion
Smile lines are a natural testament to a life full of expression. While aging inevitably brings changes to our skin, numerous effective strategies exist, from diligent prevention and natural care to advanced cosmetic treatments, allowing you to manage their appearance if you choose.
Remember that consistency with skincare and sun protection forms the foundation of healthy skin at any age. If considering procedures, a consultation with a qualified professional is the best starting point to explore options tailored to your unique needs and goals. Ultimately, whether you embrace your lines or seek to soften them, the goal is to feel confident and vibrant in your skin.
